(646) 918-8073

I am on the do not call list
the number 646 918 8073 calls all hours just received one today 4/1/2011 at 6:42 pm on my cell.
How do I have this stopped or blocked. I now have 5 calls from different numbers calling on my cell, I'm about to cancel my cell phone and go back to the old wall phone. For the life of me I can't understand what kind of person that gets his kicks this way.

Called me twice or three times a day previously and at last I answered, they offered to be a part time video game tester... I hung up on them. Caller had a heavy middle eastern accent.
